IOS18 - Arial chinese text NOT displaying

Users are reporting that text is not being displayed after updating their OS to 18.

Did a google and it seems there are changes to fonts in IOS18.

How to fix this issue?

We are using legacy “TEXT” UI element with arial text.

Hi I have had a similar problem with my app on iOS for mandarin localization. On my device’s settings, I added the Chinese to the preferred languages, then I downloaded the “PingFang” system fonts. After this the missing characters displayed correctly.
